1973 Invention PLATO Notes is created by 17-year-old student Dave Woolley at the Computer-based Education Research Laboratory at the University of Illinois, as a conferencing and bulletin board forum system for communicating with the user community. In 1976, Notes expanded to enable any user to create a "notesfile" on any subject. PLATO Notes would serve as the inspiration for Lotus Notes developed by former PLATO users Ray Ozzie, Len Kawell, and Tim Halvorsen. (9 ч 38 мин, 10 янв 1973 г. – 13 ч 58 мин, 20 март 1973 г.)
